Morison ([email protected]) Abstract. Climate change has implications for the capacity of the many small shallow ponds found at high latitudes to support organisms and store carbon, which in turn has important feedbacks for climate change. As carbon cycling in ponds is linked to nutrient supply, an improved understanding of pond biogeochemistry is needed. Due to logistical challenges, many studies rely on data 10 sets collected during a single campaign that may not be representative of the entire ice-free season. This study characterized spatial and temporal patterns in water chemistry in tundra ponds to determine: (1) if temporal variability in pond chemistry exceeded spatial variability; (2) if temporal variability existed, whether all ponds (or groups of ponds) behaved in a similar temporal pattern, linked to season or hydrology; (3) if spatiotemporal variability in pond biogeochemical signatures could be used to make inferences about processes occurring within ponds and between ponds and surrounding peatlands. Six shallow 15 ponds located in the Hudson Bay Lowlands region were monitored ~biweekly throughout the ice-free season (May 1-October 31, 2015) for concentrations of nitrogen species and major ions. Temporal variability exceeded spatial variability (variation among ponds) in pond concentrations of most major ions and dissolved organic nitrogen, which appeared to be driven by the evapoconcentration and dilution of pond water. In contrast, the dissolved inorganic nitrogen species were not directly related to pond hydrologic conditions and were instead likely mediated by biological processes within ponds. This work provides an 20 improved understanding of the relative controls of internal and external drivers of pond biogeochemical patterns, and highlights the importance of the highly variable seasonal hydrology. This work also provides insight for future field sampling campaigns. 1 Introduction Small, shallow freshwater bodies (<1 km2) across the circumpolar north are ubiquitous in the landscape (Muster et al., 2013; Dyke and Sladen, 2010; Macrae et al., 2014). These ponds maintain the capacity to store and exchange carbon (C) (Macrae et 25 al., 2004; Abnizova et al., 2012), act as habitat (Smol and Douglas, 2007), and mediate the landscape energy balance (Chapin et al., 2000), despite being historically underestimated in total areal coverage. These tundra ponds are highly sensitive to climate change (Schindler and Smol, 2006), which may impact their hydrology and biogeochemistry. This has implications for their ability to support organisms and store or cycle C, which in turn has important feedbacks to climate change. Thus, an improved understanding of pond biogeochemistry is needed. 1 Biogeosciences Discuss., doi:10.5194/bg-2017-142, 2017 Manuscript under review for journal Biogeosciences Discussion started: 11 May 2017 c Author(s) 2017. CC-BY 3.0 License. Climate change may impact pond biogeochemical conditions by modifying pond hydrologic and thermal conditions, as well as pond-catchment connectivity. In permafrost systems, recent work has focused on the impact of climatically-induced permafrost thaw on lake and pond chemistry (Vonk et al., 2015) over a timescale of decades, generally showing increasing concentrations of ions indicative of deeper flowpaths and weathering processes (Kokelj et al., 2009). Lougheed et al. (2011) 5 examined changes in tundra pond chemistry over 40 years in Alaska and observed substantial increases in inorganic nutrients, which were attributed to a thaw-driven release from shallow permafrost and increased atmospheric nitrogen (N) deposition. In addition to changing chemical contributions from thawing catchments, the water balances of ponds are sensitive to climatic changes that impact the ponds directly as well as indirectly through changing catchment hydromorphology (Walvoord and Kurylyk, 2016). In particular, with permafrost decay, thermokarst expansion acts as a mechanism for lateral seepage and loss 10 (eg, Yoshikawa and Hinzman, 2003) leading to increased connectivity, potentially modifying seasonal biogeochemical trajectories (Abbott et al., 2015). Elevated levels of nutrients and/or ions may impact the C uptake function of ponds via primary productivity, which has been shown to be nutrient limited in subarctic and arctic freshwater bodies (Levine and Whalen, 2001; Bergström et al., 2005; Bergström, 2010; Bonilla et al., 2005; Symons et al., 2012). Indeed, increased nutrient loading to ponds may either bring about an increase in pond primary productivity (Levine and Whalen, 2001; O’Brien et al., 15 2005) or may lead to a decrease through increased turbidity and suboptimal conditions for photosynthesis (northern Sweden, Ask et al., 2009; northern Québec, Roiha et al., 2015). Although climate change may lead to long-term changes in pond permanence and hydrologic exchange, pond hydrologic storage can also vary greatly over the course of a single season or between different hydrologic years (Morison et al., 2016, Woo and Guan, 2006). Indeed, pond storage often reflect the highly variable local climatic conditions, and can both desiccate 20 completely (e.g. Bouchard et al., 2013; Smith et al., 2005) and spill over bankfull storage and/or coalesce (Macrae et al., 2014). The hydrology of ponds is closely tied to chemical concentrations, both directly through physical processes (i.e. dilution and evapoconcentration; Borghini et al., 2013) and indirectly through mediating environmental factors that control the rate of biogeochemical processes (e.g. variable pond depth controlling the diurnal water temperature amplitude; Smol and Douglas, 2007). Mazurek et al. (2012) sampled shallow ponds over several summer seasons in Svalbard and found ionic concentrations 25 increasing in ponds over the summer months, coincident with pond drying. White et al. (2014) monitored ponds at three time steps over the ice-free season and related pond seasonal biogeochemical trajectories to pond morphology and pond-peatland connectivity. Given the significant control of hydrology on pond biogeochemistry, and the highly variable hydrology experienced by ponds within a single season, an improved understanding of seasonal patterns of pond hydrochemistry is needed to better understand potential pond responses to climate change. 30 Recent approaches to characterising shallow pond biogeochemical processes across Arctic, Antarctic, and alpine permafrost settings have used three to four water samples from each lake or pond, taken at different points of the ice-free season to represent “early-season”, “mid-season”, and “late-season” conditions. Other approaches have relied on a single annual sample to characterize various geochemical indicators of ponds, such as nutrient status, carbon dynamics, major ion and metal concentrations, often sampling many ponds and lakes (often 10 – 100) at that single time period (Table 1). Given the variability 2 Biogeosciences Discuss., doi:10.5194/bg-2017-142, 2017 Manuscript under review for journal Biogeosciences Discussion started: 11 May 2017 c Author(s) 2017. CC-BY 3.0 License. in pond storage and hydrological conditions over the course of an ice-free season, it is important to frame the results of pond chemical analyses in the proper hydrologic context, and further, to be prudent in generalizing pond geochemical process from samples taken in different hydrological periods. Beyond broad spatial sampling campaigns of many periods at a coarse temporal resolution, less is known about the amplitude, drivers, and total variation in seasonal and event chemographs of 5 shallow ponds in remote northern catchments, despite their importance in driving key ecological functions across the circumpolar north. The objectives of this study were to characterize spatial and temporal patterns in the chemistry of a suite of tundra ponds to determine if: (1) temporal variability exceeded spatial variability throughout the open water season; (2) temporal variability existed, whether all ponds (or groups of ponds) behaved in a similar temporal pattern, linked to season or hydrology; and (3) 10 spatiotemporal variability in pond biogeochemical signatures could be used to make inferences about processes occurring within ponds and between ponds and surrounding peatlands. This information will improve our understanding of hydrobiogeochemical processes in tundra ponds, particularly in terms of seasonal patterns, and, will aid in developing appropriate sampling designs in future. Further, this study provides a geochemical survey of six ponds in the Hudson Bay Lowlands region at two unprecedented temporal scales (bimonthly, spanning an ice-free season, in addition to diurnal samples 15 spanning an intense rainfall-runoff event. 2 Methods 2.1 Study site and sampling design This study was completed in the Hudson Bay Lowlands, approximately 20 km East of the town of Churchill, Manitoba, Canada. The regional climate is strongly influenced by the close proximity to Hudson Bay (Rouse, 1991), with average

  • Century Feminism: a Jungian Exploration of the Feminine Self
    20th Century Feminism: A Jungian Exploration of The Feminine Self by Christopher Alan Snellgrove A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama August 4, 2012 Keywords: Carl Jung, Virginia Woolf, Toni Morrison, Margaret Atwood, Archetypes Copyright 2012 by Christopher Alan Snellgrove Approved by Jonathan Bolton, Chair, Associate Professor of English Dan Latimer, Professor Emeritus of English Susana Morris, Assistant Professor of English Abstract The following work uses the theories and methods provided by Carl Jung as a way of analyzing works by three women authors: Virginia Woolf’s Orlando, Toni Morrison’s Beloved, and Margaret Atwood’s The Handmaid’s Tale. The primary Jungian notion featured is that of self-actualization—the process by which a person has achieved a sense of wholeness uniting their body and mind to the greater world. Specifically, I examine how the protagonists and antagonists of these texts either complete their Jungian journey towards actualized wholeness. In order to do this, I focus greatly on Jung’s notion of archetypes, and how they either help or hinder the journey that these women are on. A large part of the analysis centers on how actualization might be defined in feminine terms, by women living in a world of patriarchal control. As such, this work continues the endeavors of other Post-Jungians to “rescue” Jung from his own patriarchal leanings, using his otherwise egalitarian theories as a way of critiquing patriarchy and envisioning sexual equality. Jung, then, becomes an interesting bridge between first, second, and third-wave feminism, as well as a bridge between modernism and post-modernism.

Like other nucleocytoplasmic large DNA viruses, ASFV encodes a transcription apparatus including a eukaryote-like RNA polymerase along with a combination of virus-spe- cific, and host-related transcription factors homologous to the TATA-binding protein (TBP) and TFIIB. Despite its high impact, the molecular basis and temporal regulation of ASFV tran- scription is not well understood. Our lab recently applied deep sequencing approaches to characterise the viral transcriptome and gene expression during early and late ASFV infec- tion. We have characterised the viral promoter elements and termination signatures, by mapping the RNA-50 and RNA-30 termini at single nucleotide resolution. In this review, we discuss the emerging field of ASFV transcripts, transcription, and transcriptomics. Introduction to African swine fever The emergence of African Swine Fever (ASF), caused by ASFV, was first documented almost 100 years ago in Kenya after the disease transferred from warthogs to domestic pigs, which developed a highly lethal haemorrhagic fever; unfortunately ASFV remains endemic in Sub-Saharan Africa [1].

  • Wreaths of Time: Perceiving the Year in Early Modern Germany (1475-1650)
    Wreaths of Time: Perceiving the Year in Early Modern Germany (1475-1650) Nicole Marie Lyon October 12, 2015 Previous Degrees: Master of Arts Degree to be conferred: PhD University of Cincinnati Department of History Dr. Sigrun Haude ii DISSERTATION ABSTRACT “Wreaths of Time” broadly explores perceptions of the year’s time in Germany during the long sixteenth century (approx. 1475-1650), an era that experienced unprecedented change with regards to the way the year was measured, reckoned and understood. Many of these changes involved the transformation of older, medieval temporal norms and habits. The Gregorian calendar reforms which began in 1582 were a prime example of the changing practices and attitudes towards the year’s time, yet this event was preceded by numerous other shifts. The gradual turn towards astronomically-based divisions between the four seasons, for example, and the use of 1 January as the civil new year affected depictions and observations of the year throughout the sixteenth century. Relying on a variety of printed cultural historical sources— especially sermons, calendars, almanacs and treatises—“Wreaths of Time” maps out the historical development and legacy of the year as a perceived temporal concept during this period. In doing so, the project bears witness to the entangled nature of human time perception in general, and early modern perceptions of the year specifically. During this period, the year was commonly perceived through three main modes: the year of the civil calendar, the year of the Church, and the year of nature, with its astronomical, agricultural and astrological cycles. As distinct as these modes were, however, they were often discussed in richly corresponding ways by early modern authors.
